From the Independent (via Eric Worrall at WUWT)
In his speech, Mr Macron also called for an EU tariff on goods imported from countries or companies that do not share its climate goals, and pledged to work to raise the cost of carbon within the EU to €30 a tonne.
The EU INDC submission to COP21 Paris states
The EU and its Member States are committed to a binding target of an at
least 40% domestic reduction in greenhouse gas emissions by 2030
compared to 1990,
Most INDC submissions do not state they will reduce their greenhouse gas emissions. As a result, even if the proposals are fully met (and the EU is unlikely to meet its target) then emissions are forecast to be higher in 2030 than they are today. This graphic from the UNEP Emissions Gap Report published at the end of October demonstrates the situation quite nicely.
So President Macron is wanting sanctions not just against the USA, but most of the world as well? This includes China, India, nearly every African country, most countries in SE Asia, the Middle East nations and some other nations besides. Or is it just those who stand up to the useless European climate policies, that are benefiting large businesses with subsidies financed disproportionately by the poor? The rhetoric includes “companies”, on whom sanctions cannot be applied. Further, the €30 carbon price is equivalent to €0.10 on the price of petrol (gasoline). How is a small rise in the cost of fossil fuel energy from a group of countries with less than 10% of GHG emissions going to save the world? As economics Professor Richard Tol has estimated, to achieve the targets would require a global carbon tax from 2020 of $210 and then escalated by 4-6% a year until fossil fuels were unaffordable. Chancellor Angela Merkel claims “Climate change is by far the most significant struggle of our time.” (Independent again). The falsity of this claim is shown by political newcomer President Macron’s trying to marginalize and silence opponents with empty and ineffectual threats.

/ 18/11/2017All politicians make daft statements about climate change. What makes Macron different is that he sees himself as a man of action, not content to outline policy but determined to put it into effect immediately. That’s why he reacted to Trump’s withdrawal from the COP21 Paris Agreement by immediately convening an international climate conference for December 12th. Nobody cares that Fiji’s COP23 Bonn meeting was a boring non-event. Macron can’t let the same thing happen in Paris in four weeks’ time, because, well, because he’s Macron.
The environment and the future of France’s bewildered-looking Ecology Minister (the most popular in the government) has been the big subject in the French media for the past two weeks, due to the minister’s decision to renege on a promise to reduce France’s reliance on nuclear from 75% to 50% by 2025. French journalists, who can’t tell their ozone hole from their elbow, seem to think that this is a bad thing for the climate. Another environmental failure, like no-one turning up to his conference, would be a big black mark, and might force Macron to do something drastic, like sparking off a Middle East war.

/ 18/11/2017Thanks Geoff for your comment. Living in France, you have a better understanding than I. It would seem that Macron is different he wants to be perceived as actually doing something, rather than being perceived as just signing a bit of paper, or putting up a common front.
