This presentation was made by Carlos Munoz Pina, Mexico, at the Paris Collaborative on Green Budgeting Experts Workshop held at the OECD, Paris, on 20 June 2018
2. • Choice of instruments: Environmental taxes (Prices) vs Cap&Trade
(Quantities)
• In practice, environmental taxes seem to be the most attractive choice for
most emerging markets. However, instrument mixes are valuable.
2
The rationale for environmental taxes
Taxes Cap & Trade
Higher certainty on costs,
higher uncertainty on outcomes
Higher uncertainty on costs,
higher certainty on outcomes
Collection is easier as it can rely on
existing capacities and institutions
Developing deep and liquid markets
is a challenge
General application
Issues of initial, and subsequent,
allocations
3. 1. Strategic complement for environmental policy.
2. Green revenue (better to tax bads than to tax goods)
• Choice of instruments: Prices vs Quantities (Weitzman)
– Quantities (Cap&Trade) give certainty to outcome, can have uncertain costs.
– Prices (environmental taxes) give certainty to costs, but outcomes may vary.
– Descentralized incentives: wider reaching than large emittors’ regulation or
markets, plus lower implementation costs. -Push and pull-
• Fiscal policy: raise revenue with minimum welfare loss.
– Ramsey rule: Low elasticity goods and services.
– Double dividend: Reduce negative externalities, and less DWL in others.
The rationale for environmental taxes.

5. • Part of a broad fiscal reform that was sent to Congress in 2013:
o A fixed amount per ton of CO2 content, for all fossil fuels.
o The tax was set at US$ 5.7 per ton of CO2 (average of most relevant
carbon markets: EU-ETS, California, New Zealand).
o Rates are adjusted annually for general inflation.
5
Mexico’s Carbon Tax
6. • Tax administration is straightforward:
o The carbon tax is paid at the production or import stages and can
be credited, except for the final sale (similar mechanics to a VAT).
o Collection and auditing is done by the revenue collection agency
(SAT), on the same terms as other excise taxes.
6
The Carbon Tax in Mexico
7. • Well received in Congress and was approved with some changes:
o Lower average carbon pricing (US$3.7 per ton of CO2).
o Natural gas was taxed at zero. Argument: cleanest fossil fuel.
o Only coal used as fuel is subject to the tax.
o The tax can be paid with internationally-recognized certificates of
emission reductions, at market values.
• To comply with international treaties, jet fuel is also taxed at zero (through
Executive decree).

10. • Law allows to pay in-kind with CER.
• Payment according to equivalent value of CERs, not equivalent
of tons reduced (discussion).
• Concrete way for “conditional” goals for NDCs.
• Mexican government would act as aggregator of supply, and purchasers
would own the CERs and comply with conditionality.
• Uses Clean Development Mechanism (CDM) registry and
verification process.
Paying the tax with certified emission reductions
11. • Support from domestic think tanks and NGOs was important in media and
policy discussions.
• Build on previous success. Mexican Congress had approved its Climate
Change Law in 2012, where carbon taxes were mentioned as potential
instruments.
• Having the “greenest” option (natural gas) taxed at zero increases political
acceptance (similar to the tax for pesticides, part of the same bill).
• Neighbors matter: lower fuel taxes in some neighboring countries reduced
maneuvering room.
• Constant discussion on earmarking, vs green expenditure.
11
First Policy lessons from the carbon tax
13. • Approved to start operating in 2014 (half rates) and 2015 (full rates):
o Acts in the space of an existing 0% VAT rate for agrochemicals.
o Environmental signaling needed to classify compounds according to
impact on human health and wildlife.
o World Health Organization (WHO) classification provides robust
environmental gradient.
o Environmental tax is defined as a percentage of value, instead of kg.,
because of monitoring complexity, and varies according to WHO and
Mexican classification of toxicity of pesticides.

19. Mexico’s peer review on inefficient fossil fuel subsidies
19
• Part of the G20 commitment to phase-out fossil fuel subsidies, Mexico joined
Germany in a peer-review analysis of its efforts.
• Both reviews were completed in 2017 and valuable lessons were drawn from
the process, especially regarding the institutional setup for the phase-out and
current remaining challenges.
• Following on the paired effort of the US and China, and Mexico and Germany,
this year is the turn of Italy and Indonesia, supported by our analysis teams.

23. Defining Economic inefficiency,
subsidies vs. tax expenditures
23
Three elements for the analysis:
• Inefficiency inducing subsidies refer to pricing below opportunity cost
(price-gap approach). The comparison would be with fuels’
international reference prices.
• Tax exemptions are not subsidies, in the economics sense. If they differ
from the Ramsey rule they might be sub-optimal taxes, but not
inefficiency-inducing subsidies. However they are still presented here
for comparison purposes
• We also look at tax provisions to producers of hydrocarbons, in
particular in light of the recent opening of the upstream sector in
Mexico. The competitive bidding process internalizes the revenue loss
effect.
25. Self-report and peer-review Conclusions
25
1. Through a prudent and gradual fiscal policy Mexico was able to completely
phase out general fossil fuel subsidies, fulfilling this G20 commitment.
2. The country gradually moved from an subsidy of 1.8% of GDP in 2008 to a
positive taxation amounting between 1.2% and 0.7% of its GDP.
3. Key in the success of this policy has been responsibly redistributing public
spending away from inefficient subsidies towards more productive and
socially progressive policies.
4. Mexico introduced resiliency into the general fossil fuel subsidies phase-out
through institutional changes part of its ambitious Energy Reform:
• reforming excise taxes,
• introducing a carbon tax,
• and redefining rules for its national petroleum company.
26. current challenges
26
• Tax accreditation remains an element to observe and analyse.
• Structural changes in Mexico reinforce the fossil fuel phase-out.
• From December 2017 onward, gasoline and diesel prices are now fully
determined by markets.
• LPG prices had the same liberalization in January 2017,
• the rest of fuels have had market prices for more than a decade.
• Price volatility is a challenge, especially in the transition to market prices.
• The response has been the implementation of an instrument of fiscal
smoothing through a transparent instrument of weekly stimulus given to
the Excise tax rate.
• Keeping net revenues within target, the instrument has been successful,
and supportive of the transition, for both new entrant firms and
consumers.

Recent developments
The subsidy was eliminated starting in mid-2014, and 2015 was the
first complete year for which positive revenues were generated.
Outlook
Since 2016, the fuel tax is a quota per liter. Starting in 2017, prices
will be gradually allowed to be set by market conditions. All of these
provisions preclude observing subsidies in the future.

Outlook
The Rural Energy Law requirements are still in place and the benefit is not considered an
inefficient subsidy.

Special tax treatment in the Hydrocarbons Revenue Law:
• An exploration and production company can consolidate results across different contracts for
corporate income tax (CIT) purposes.
• For CIT purposes, an accelerated depreciation is provided : 100% depreciation rate for exploration
investments and 25% for wells.
• For deep-water projects, contractors are allowed to carry forward losses for up to 15 years (the
general treatment is ten years).
34. LPG: Eliminating subsidies, only if targeted support
34
• In 2016 liberalizing LPG imports. Until 2015 Pemex was sole producer, importer.
• In 2017, liberalization of prices. Could be done beforehand in 2016, “conditional on
targeted support for consumers”.

• At any point in time, federal government retains the right to establish maximum
prices if Federal Competition Commission detrmines that there is not enough
competition in the national or regional markets.
35. A decade of fossil fuel subsidies for LPG
35
• LPG consumers in Mexico had enjoyed significant subsidies for almost a decade.
PEMEX as sole producer and importer allowed total control over pricing policy.
Social relevance and high weight in consumer index, made stable prices a policy
priority, and choice, for 3 administrations.
• Small but steady price increases sought to close a growing gap. It only stopped
whenever intnt prices dropped. In this context Mexico’s Energy Reform proposed
liberalization, gradual liberalization.

36. How to liberalize and protect poorer households?
36
• Keeping prices stable and below international prices transferred significant amount
of subsidies to all consumers. Liberalization of prices in 2017 would either
eliminate or require subsidies to be explicit.
• As in most cases in energy consumption, higher income households consume more
energy –directly and indirectly- so they receive the greatest transfers.

• Having small steady price increases were a politically acceptable way to
reduce the ammount of subsidies.
• Providing targetted subsidies to the lowest quintile of the population would
avoid a negative shock to those living in poverty, while allowing the new
market to operate with a stronger fiscal situation.
37. Falling international fossil fuel prices made it unnecesary
37
• Currently domestic price is 34% above international reference prices (PEMEX opportunity
costs). Moreover, Federal Revenue Law would allow a price increase of 3% in 2016. Given
LPG future prices this would mean a surplus of more than 1.6 billion dollars in 2016.
• Opening imports would allow the market to work pushing down prices to their efficiency
levels. Given the oligopolistic structure of LPG markets, competition policy must activel and
ready for intervention.

38. Conclusion
38
• In México, both the Executive and Legislative actively proposed liberalization of LPG prices
but only conditional on having a targetted support system in place.
• The evolution of international markets made it unnecessary, but the mandate was in place if
needed. The potential scheme provided certainty in the transition, including focusing
subsidies on those that most needed.
• Lesson for other economies: politically feasible, best way to ensure action is taken. Fiscally
responsible.
