1) The Citizens Climate Climate Lobby has been around ten years, and it currently has a bill in Congress that has bipartisan (1 Republican) support: The Energy Innovation and Carbon Dividend Act (http://energyinnovationact.org/). With this plan, all the revenue from a carbon tax* is directly returned to citizens as a yearly check--no enlargement of the state. This is the organization cofounded by NASA scientist James Hansen, who first testified to Congress about the perils of climate change over 30 years ago.
2) If you're a millennial/gen Z, and you're more skeptical of a market-based solution, the Green New Deal and Sunrise Movement are making waves. Rather than a concrete policy in Congress, they have a set of principles/values that they are pushing forward. This includes economic and social justice issues.
*Carbon pricing (which can come in the form of a tax or cap and trade) is the single most effective mechanism to address climate change. The idea is to internalize the _real_ costs of climate change into the price we actually pay--ramping up the price on carbon over time until it is prohibitively expensive to use fossil-fuel-expensive products, and incentivizing the economy to adapt. That fundamental price signal, where renewable energy becomes cheaper relative to fossil fuels (and similarly less fossil fuel-intensive goods are cheaper relative to fossil-fuel-expensive ones) reverberates throughout the economy. However, it's worth noting that while this solution should theoretically appeal to Republicans, almost none have stepped forward...
