Effect of rubber price on breakeven carbon prices in dense and open forests. The response of breakeven carbon price to rubber prices under the “No timber logged” scenario is shown for a dense and b open forests. Each dot represents the outcome of one model iteration. Grey dashed lines indicate real-world carbon prices, following Fig. 3. Red lines represent a linear model relating breakeven carbon price to rubber price index (with grey shaded SE, too narrow to be visible), where an index value of 1.0 is the 10-year mean rubber price (2003–2012)
