• The impacts of climate change are already being felt, and limiting warming by 2 degrees is a minimum
• Limiting warming by 2 degrees will require 17Gt of abatement by 2020
• This will require action from developed and developing countries
• Substantial funding to the developing world (€65-100bn pa) is required over the next ten years
• “Low carbon growth plans” are required to enable both the private and public funding flows to developing countries

About Project Catalyst
• Initiative of the ClimateWorks Foundation, a global, non-profit philanthropic foundation headquartered in San Francisco, California with a network of affiliated foundations in China, India, the U.S., and the European Union
• Launched in May 2008 to provide analytical and policy support for the United Nations Framework Convention on Climate Change (UNFCCC) negotiations on a post-Kyoto international climate agreement
• Provide a forum where key participants in the global discussions can informally interact, conduct analyses, jointly problem solve, and contribute ideas and proposals to the formal UNFCCC process
• Organized in working groups: mitigation, adaptation, technology, forestry, climate-compatible growth plans, and finance with a total of about 150 climate negotiators, senior government officials, representatives of multilateral institutions, business executives, and leading experts from over 30 countries. Analytical support from the international consulting firm, McKinsey & Company

Scientific evidence suggests that a 450ppm CO2e pathway with over-shoot gives a 40–60% probability to limit global warming to 2 degrees

• 450ppm is not safe – it has a 40–60% pro-bability of warming exceeding 2oC
• Even 2oC will require signifi-cant investment in adaptation
Peak at 550 ppm, long-term stabilization 550 ppm
Peak at 510 ppm, long-term stabilization 450 ppm
Peak at 480 ppm, long-term stabilization 400 ppm

*US – 17-28% below 2005 level by 2020; EU – 20-30% from 1990 level by 2020 (2.3 Gt); China - Reduce energy consumption per national income by 20% between 2005–10 (0.8Gt), and again between 2010-2015; Russia - stabilise emissions at ~30% below 1990 (0.7 Gt); Brazil - Reduce deforestation rates by 70% by 2017, equivalent to 4.8b tons less CO2 emitted cumulatively (0.7 Gt); Japan - Reduce 80% by 2050 from current levels (0.7 Gt); Canada - 20% reduction from 2006 level by 2020 (0.3 Gt); Mexico - Reduce emissions from 2002 levels by 50% by 2050 (0.3Gt), plus proposals from 12 smaller Annex 1 countries and South Korea. Assumptions have been made on timeline and pathway to calculate abatement in 2020

Remaining abatement feasible in developing countries (NPV positive) – may be supported by developed countries
Support for incremental costs needed, e.g., concessional loans, grants, payments
Support needed for capacity building and loans
for capital investment where required
Remaining abatement feasible in developing countries (NPV negative) – may be financed by developed countries
Carbon credit purchases to meet 25% target
Abatement feasible in developing countries – may be financed by developed to meet target commitments(e.g., via CDM)

Climate Compatible Growth Plans (CCGPs) are a way to identify and support developing country mitigation and adaptation actions
Differentiation: Both developing + developed
Process: Support, best practices, review, MRV
Content: Priorities, policies/measures and international support•
Focus: Development, mitigation + adaptation
CCGP (=climate compatible
growth plans)
Time horizon: Long term and short/medium term
15
The elements of an LCGP
• National circumstances and current development plans
• Assessment of vulnerability to climate change and how future climate change will affect it
• Most recent GHG inventory
• Long-term vision for an economy with low GHG emissions and low vulnerability to climate change
• Plan for specific investments in making the economy and the infrastructure less vulnerable and measures to adapt existing infrastructure to the changing climate
• GHG mitigation plan containing:
– Projection of GHG emissions under BAU scenario for the most important economic sectors
– Scenario the country can achieve without assistance
– Scenario for which it would require international support.
• NAMAs and NAPA’s the country wishes to undertake
• Incremental cost of the individual NAMAs and NAPAs and all technology, financing and capacity building support needed to implement the plan.
Strategic plan to assist the country in shifting its development path to a low carbon and climate resilient economy and achieve sustainable development
Based on the socio-economic and development priorities of the country
Includes a strategic vision (long-term component) as well as that specific actions to be undertaken to get on a low carbon, climate resilient pathway (short and medium term component)

Solar technology provides advantages for Africa A Global Deal could . . .
Opportunities for leap-frogging exist which provide multiple advantages to support African development
•Low levels of electrification in Sub-Saharan Africa
•Off-grid solar technology is commercially available:
–Cost-effective in remote areas
–Faster deployment in remote areas
–More reliable
–Environmental and security benefit
•Provide funding
•Widen access to loans
•Provide technology access
•Support research
•Overcome IP barriers
•Develop institutions and processes
