Re: Addressing climate change

the Global Commission on the Economy and Climate calculated what climate change will cost the world... or conversely, how much humanity would save by becoming more sustainable - tallied the number at $26 trillion in savings by 2030.

key findings:

    - Time is running out; extreme damages from future climate change are being locked in. If humanity isn’t on a sustainable trajectory by 2030, limiting global warming to 2 degrees Celsius — the common international target — will be rendered impossible.
    - The developing world needs tons of new infrastructure; the developed world has tons of infrastructure nearing the end of its life span. That means the world is on the verge of an enormous infrastructure boom that will lock in emissions outcomes for the next 50 to 100 years. The next few years are vital: “The world is expected to spend about US$90 trillion on infrastructure in the period up to 2030, more than the entire current stock today. Much of this investment will be programmed in the next few years.”
    - In all five areas the report closely examined — energy, cities, food/land use, water, and industry/innovation/transport — shifting to sustainable technologies and techniques would save trillions of dollars through 2030 in increased productivity, innovation, and reduced health costs. Sustainability costs less.
    - The impacts of climate change and the impacts of a transition to sustainability will both be concentrated in particular countries and communities, so every policy and infrastructure decision needs to be made with equity in mind.
    - Progress is underway in many areas, especially in energy, but it is patchwork, inconsistent, and entirely insufficient to achieve shared long-term goals.
    - Policymakers worldwide need to price carbon, roll back fossil fuel subsidies (and other policies that impede sustainability), invest in sustainable infrastructure, harness the private sector, and protect vulnerable communities.
